Self-reported complication rates following primary total hip arthroplasty in Ireland: fact or fiction

Abstract

There are little data available on complication rates following primary total hip arthroplasty (THA) surgery in Ireland. To determine self-reported complication rates and national data for primary THA. A postal questionnaire surveyed Irish orthopaedic association consultant members. Additional data were obtained from the economic and social research institute (ESRI). We achieved an 83% response rate. 5,424 THAs were self-reported. Mean dislocation rates were 1%, but higher using a posterior surgical approach (p < 0.05). Mean deep infection rates were 0.4%. 29% were MRSA. No reduction was reported from additional barrier prophylaxes. Mean venous thrombo-embolism (VTE) rates were 3.5%. No reduction was reported from commencing prophylaxis preoperatively or extending treatment duration. National rates for dislocation, deep infection and VTE were 25.7, 0.87, and <0.1%, respectively. The creation of a National Hip Register is strongly recommended. A register would improve surgical practices and patient outcomes, and provide significant healthcare savings.
